Print execution indicator
In my health practice database I have created a form letter that advises referral agents that their patients have contacted me for services. When I have all of the referral agent's contact info I click a button and the letter prints. I don't always have enough iinformation to send a letter, meaning that I will send one for some patients but not others.
Is there a way to create some sign or indicator (eg, an icon, a radio button) that the letter has already been printed so I don't do it twice?
